The matters involving Dolphins guard Richie Incognito and tackle Jonathan Martin go well beyond the field of play, but it doesn’t mean that the departure of both players from the team leaves the Dolphins in need of some help on the offensive line.

They addressed that need on Tuesday. Mike Garafolo of Fox Sports reports that the team will sign guard David Arkin off of the Cowboys’ practice squad to fill the spot on the roster opened up when Incognito was suspended for conduct detrimental to the team.
